Merry-go-round Pumps

Joy pumps are an innovative concept of pumping water from bore-well, a sump or a rainwater harvesting tank. It uses playful energy of children or operators collectively to pump water. Merry Go Round pumps use force lift technology to draw water from a water source to an overhead tank above the ground level for storage and distribution. It doesn’t require electric power. Merry Go Round pumps work on the same technology and use the reciprocating motion to move the valves of a water cylinder. These pumps use a specially designed mechanism to convert the revolving motion to a reciprocating one. The technology below the ground is same as the hand pump technology, hence making it very easy to maintain at village level.
